IMPROVEMENT IN MACHINE FOR PRINTING ON SPOOLS. -.aow

The Schedule referred to in these Letters Patent and making part of the same To all whom turey concern Beit known-V that we, GARDINER HALL, Jr., of South Williugton, in the county of Tolland and State of Connecticut, and GEDRGE W. AVERELL, of the city, county, and State ot' New York, have invented a new and useful Improvement in Machines for Print,

ing Spools; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had tothe accompanying drawings forming part of this specification.

This invention relates to a new and useful improvement in a machine for' printing or labeling spools for holding thread or other material of like nature, and consists in the use ofa series of dies, and in connection therewith, the several mechanisms for producing the movements necessary to accomplish the object in view, the main object being to print both ends of the spool, directly upon the wood, while the spool is passing through the machine, but which mechanism may be applied to printing, upon paper upon the ends of the spool, or which (with slight modifications) maybe applied to printing upon one instead of both ends of the spool, or to printing the ends separately, either upon the wood or upon paper, or other material, on

-the ends of the spool, as will be hereinafter more fully described.

In the accompanying drawing- Fignre 1, sheet I, represents a side elevation of the machine. i

Figure 2, sheet I, is a vertical cross-section of fig. 3, on the line :c x. l

Figure 3, sheet II, isa section of iig. l ou the line Figure 4, sheet II, is a detailed view of the mech anism by which the intermtting motion is produced- Similarletrs of reference indicate corresponding A is the platform, upon which the operating parts of the machine are supported.

B B are stationary heads, of cylindrical form, which are supported ou suitable stands, and which are `connected together above the central space between H is a skeleton spool-wheel, which is made to revolve with an intermitting motion between the heads B B on the shaft I. lhis shaft is placed at right angles with the shafts D D', and'is supported by the stands which support the headsB B.

The intermittiug motion of the wheel H is produced by means of the ratchet-wheel J. which is fast on the shaft I.

K is a plate, loose on the shaft I, outside of the ratchet-wheel J, which is given an oscillating motion from the wrist-pin L in the gear-wheel E', by means of the connecting-rods M N and the horizontal swaybar' O.

Cllhe plate K carries a pawl, (seen in dotted lines in fig. 4,) which engages with thcfeeth P of the wheel J, and rotates the shaft I and wheel H with an intermitting motion. v.

Q is a spring, which engages with the notches R in the outer rim of the ratchet-wheel, for preventing back motion and holding the wheel steady.

While the shafts D D' are given a constant motion, the skelctomwheel H, which carries the spools, is stopped at uniform periods, and' remains stationary while the spools are received and while they are printed.

S represents the spools, which .are fed into the wheel H from the inclined spout T,-which spout is supported by the stand T.

U is a feed regulator, which hears upon the spools, and prevents more than ouespool from entering the wheel H during one iutermittinnr period.

Thisregulator is pivoted to the'stand U, and is in the form of a bell-crank.

One arm of the bell-crank reaches to and bears upon or against. the spools, while theotheris operated upon by the cam V, ou the end of the shaft D;

When this cam comes in contact with the arm, it raises the other arm and allows the spools to roll down far enough lto allow one spool to enter the wheel when the cam leaves the upright arm. When the cam leaves the upright arm, the spring V' acts upon the other, and brings it down in contact `with the forward spool in the spoilt. This movement is timed so as to exactly correspond with the resting periods of the spool-Wheel.

The spool falls into the cavities Y, which cavities may be either circular' or angular. The latter form is preferred, as spools of different diameters may he held steady therein.

Each cavity Y is provided with a bell-crank-shaped holder, a, one arm of which is lightly pressed upon the spool by the small spring c', while the other arm is acted upon by the double stationary cam d in such a manner that, after the spool has been printed, the

I so'that the spools may lof colors, it' desired.

other arm is released from the spools which is allowed to drop from the wheel onto the platform, or through the platform into a proper receptacle. l

f represents the dies7 which are moved horizontally toward the center, and in contact with the ends of the spools from each of the heads' B B.

In this example of our invention we use four dies, by which` we are enabled to print the ends of lthe spools in' two colors, but we do not limit ourselves to this particular number. More dies may be employed,

be printed in a greater variety g represents the die-plates, which are dovetaled into the ends of the heads B B, and are given a reciprocating horizontal lmotion by means of camsvon the shafts D D.

h represents the cams, which act against the lugs i on the die-plates. The movement' of the dies corresponds exactly with the movement of the spool-wheel,

so that at the periods of rest ofi that wheel they are brought in contact with the ends o f the spools, as

`seen in fig. 3. The spool receives one color from `one pair of dies, ,and another color from the other pair.

7' represents the inking-rollers, which are attached to the plates k on the shafts D D. They are, conscquently made to traverse the peripheries of the heads B B, from which they receive their ink or coloring matter, and pass over the ends of the dies, on which they leave the necessary quantity of ink or color for giving the impression toJthe spools. 'There may he be employed for supplying theor one end only of the spool may be printed andthe instead of movable, so that the spool would be pressed up' against lthe die; especially might this be done when the ends of the spool .were not printed simultaneously, but such methods of printing, or such modifications in the machine would not affect our invention.

Vile do not, at present, anticipate making such modifications, or adopting such methods of printing neither do we design to print on a paper surface. We intend to print directly upon the wood-surface of the spools, and to print both ends of the spool at the same time, but we do not confine ourselves exclusively thereto. y

Having thus described our invention,

We claim as new and desire to secure by Letters Pateutl 1. A feeding device T U and rotating carrier H, combined with reciprocating dies f f, constructed as and for the purpose described.

2. The combination, with a carrier-wheel,H, headers i f, and feeding channel T, of 'a revolving shalt D, cams h u, and lever u u', whereby a corresponding number of spools will always bc fed in and headed automatically.

3. The combination of the stationary cam d, with the lever a, and spring c', shown and described, to hold the spool while being imprinted, and allow its exit from the chamber at the time and in the manner set forth.

The above specification of our invention signed by us this 14th day of October, 1869.
